Code size variation between C51 Compiler Versions

Andy Massey

I have some code that compiles under C51 compiler V7.05 and uses 0E5AH of code space. The same code compiles under C51 compiler V8.06 and uses 107AH of code space. Why the increase in code space?

I am using the eval. version and working on Silabs F330 uP.

    beware of defaults.

    I once got caught in a "works with this version, lots of errors with another" and neither Keil support nor this forum caught the fact that my problem was due to a change of defaults between two versions untill I reposted the third time in 6 months.

    Try running both versions with everything specified nothing defaulted (optimixation, model, ....)
